You are right, a lot of players take an overly technical approach. And GNOME Music has a nice UI doing it differently. But on the other hand it's missing key features like gapless playback and replay gain; heck, you can't even change the music directory, it always looks into
And IMHO you're also missing the point about iTunes. It was not about the new music overview, this is great and I like it. It is about the missing sidebar, the mix-in between shop and your local music collection as well as Apple Music. These three problems make iTunes very hard to use, I am constantly looking for my music and am constantly confused about the navigation state.
